Looks like wood-fiber insulation board is coming to the USA, according to a Greenbuild update on Green Building Advisor. Agepan THD is the name of the product and it’s used as exterior sheathing for walls and roofs. Agepan boards connect in tongue and groove fashion and insulate to R-5.74 per panel (2″ x 74.5″ x 23-5/8″). The material has a high permeability (18 U.S. perms) and can be used in a wall assembly to dry to the exterior. It’s offered through Washington-based The Small Planet Workshop Store.

This is Grow Community near downtown Winslow on Bainbridge Island in Washington. The first three model homes — Ocean, Everett, and Aria — are finished and work is moving forward for the next 24 homes and two 10-unit rowhouse apartments. The eight-acre project is the first residential One Planet Community in North America (issued by U.K. non-profit BioRegional). However, in addition to this recognition, the aim is net-zero homes and an entirely net-zero energy community by 2020.

Speaking of the Cottage Series, here’s the first prefab home in this line by Method Homes with a design by Studio 29. Located on Orcas Island, the home was designed for a Washington family wanting a vacation getaway with some of the more traditional details — sleeping loft, breakfast nook, window seats, etc — typically found in classic homes of the 19th century.

If your design palette is traditional, you’ll probably like the new Cottage Series by Studio 29 and Method Homes. The Cottage Series marries craftsman style with off-site fabrication in six floor plans. These have tiered pricing based on things like the materials, interior palette, and finish packages. For a general idea, pricing is between about $215,400 – $498,300 (not including separate, optional garage and ADU structures from $23,000).

It’s been a couple years since we last checked in on the work of Seattle-based FabCab, a company that makes prefab and kit-built, eco-friendly homes and accessory dwelling units. Short for “fabulous cabin,” FabCab has several timber-frame houses under construction in Washington and recently shared photos of this two-level cabin on Camano Island. It has a timber frame, SIP panels, and a soaring water-front wall of windows.

This is Sweet Pea, a 550-square foot tiny houseboat in Olympia, Washington. It’s also the first houseboat certified by Built Green — coming in with 3-Stars — and was built by owner Mike Auderer of Olympia Construction.
